Application July 11, 1952, Serial No. 298,409

1 Claim. (Cl. 222-115) This invention relates to tooth powder cups. A tooth powder cup receives a certain amount of powder from a container, and is exposed for the entry of a tooth brush having its bristle portion aligned with said cup.

in the proposed cups, the cup was either independent of the cap of the container, so that the user had to take care of a separate cap and a separate cup.

The invention contemplates the cup as part of the cap of the container, and having the cup act to secure the cap to the container in an efficient manner to prevent access of air between the cap and container, even when the cap is on the nozzle portion of the container. In some present day tooth powders, constituents are therein contained which readily change their characteristics in the presence of air, so it is important to provide an air proof seal.

The invention consists of a closure cap at one end of a can top and locking device at the other end of said Patented Feb. 22, 1955 As these improved caps are made of suitable plastic material, of known thermoplastic or thermosetting resinoids, they have a certain amount of inherent resiliency as indicated by the arrow 27, which enables a spreading action between the portions 16 and 18. When the improved cap is placed over the nozzle 13, this elasticity enables the marginal walls to slide over the bead 11, without seriously affecting the registration of nozzle and cap, until after the curved portion 25 gets below the part 0 24 of the bead 11, when the portion, due to the inherent top, to lock the closure cap tightly on to the discharge nozzle of the can. The invention also consists in providing said locking device end with a tray or cup for the reception of the bristles of a tooth cup, after said tray or cup has been supplied with a quantity of tooth powder.

The invention will be further described, an embodiment thereof will be shown in the drawings and the invention will be finally pointed out in the claim.

In the accompanying drawings,

Fig. 1 is a perspective view of a known tooth powder container, with the improved cap thereon;

Fig. 2 is a vertical section on line 22 of Fig. 1;

Fig. 3 is a horizontal section on line 33 of Fig. 2;

Fig. 4 is a horizontal section on line 44 of Fig. 2;

Fig. 5 is a detail view of the locking device, and

Fig. 6 is a perspective view of the cap removed from the container.

Similar letters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, a known tooth powder container 10 has a circumferential bead 11 spaced somewhat below the top 12 of the container 10. The container 10 has a nozzle portion 13, with a central opening 14. Except for the bead 11, the particular construction is immaterial, and known.

The improved cap 15 consists of two portions, one 16 horizontally disposed having a bore 17 to receive with a close fit the nozzle portion 13 of the container, and the other portion '18 vertically depending from the horizontal portion 16, having a locking portion 19 to engage the bead 11.

In the embodiment, the vertical portion 18 consists of a body portion 21 and two marginal walls 22 and 23 extending from the body portion 21 towards the container 10. (Fig. 4.) These marginal walls 22 and 23 have each a portion 22a and 23a which is tangential to the rim 24 of the bead 11 and then curves towards the container to hug by the part 25 the lower portion 26 of the bead. (Fig. 5.)

resiliency snaps into that position, and provides a locking action device to hold the portion 16 of the cap 15 tightly in entirely closed position.

The portion 20 and the sidewalls 22 and 23, together with a transverse wall 28 form a shallow cup or tray, into which the powder from the can may be poured and then taken up by the bristles of the brush.

As the can is ovular in shape, the two walls 22 and 23 straddle the same, and the transverse wall 28 is correspondingly curved.

The improved cap as described provides an assurance of being held tightly to the container, and may be used as a tooth brush powder pick up, when the vertical portion is extended below the locking means, as shown in the embodiment of the drawings.

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

I claim:

In a tooth powder cup, the combination of a container for powder-like substances having an opening at one end thereof, a nozzle in said opening and a bead in the body portion thereof. said bead circumferentially surrounding said container body and being spaced from said nozzle in said opening, and a cap consisting of two substantially normally disposed portions, one of said portions having a bore to receive, when placed onto said container, the nozzle in said opening of said container, and the other of said portions being formed into a tray with a bottom and shallow side walls for the reception of the powder-like substance from said container through said nozzle in said opening thereof, at least one of said side walls of said second portion of said cap having a locking notch to engage the lower side of said bead to form locking means between the lower side of said head and said side wall having said notch and thereby to secure said cap to said nozzle, the cap being made of a material having an inherent resiliency to permit sliding of said second porton in extended position over said head and returning from said extended position, upon the continued sliding of said cap onto said container body, into a position to lock said cap onto said container, whereby said cap, when removed from said container, is adapted to be used as a powder holder and when placed onto and locked to said container by placement of said nozzle into said bore of said first portion of said cap and by engagement of said side wall having said notch with said bead on said body portion of said container, to airtightly close said powder-like substance.

within said container.
